Cartilage

Summary: If your bones moved against each other, they would rub, causing lots of pain. Eventually, the bone would wear away. To stop this happening, the ends of bones in a joint are covered with cartilage. This is a strong, smooth tissue. Fluid (liquid) in the joint keeps the cartilage slippery. This allows the bones to move without rubbing together. Tags: science student-book-7 biology Created: 2026-05-21 Last Updated: 2026-05-21
